How log to event properties without placing them in the message?

I'm current using NLog to log into Json format. I want to log event args in my logs under "eventProperties" without them being included in the message attribute.

Current nlog.config:

<target name="jsonFile" xsi:type="Console">
  <layout xsi:type="JsonLayout">
    <attribute name="time" layout="${longdate}" />
    <attribute name="level" layout="${level:upperCase=true}"/>
    <attribute name="message" layout="${message}" />
    <attribute name="eventProperties" encode="false" >
      <layout xsi:type='JsonLayout' includeAllProperties="true"  maxRecursionLimit="6"/>
    </attribute>
  </layout>
</target>

Currently call it with:

_logger.LogDebug(20, "Doing hard work! {logInfo}", t2);

Which logs the following:

{ "time": "2022-05-19 08:24:15.1395", "level": "DEBUG", "message": "Doing hard work! Test", "eventProperties": { "logInfo": {"MyProperty":"Hello2", "MyProperty2":"Testing2", "MyModel":{"MyProperty":"Hello", "MyProperty2":"Testing"}}, "EventId": 20 } }

However, I want to be able to log with the below without it stopping t2 from being logged in the eventProperties section of the JSON:

_logger.LogDebug(20, "Doing hard work!", t2);

and output for the message property to not include test in it anymore:

"message": "Doing hard work!"

How can I go about removing the property from the message without it being removed from eventProperties?

EDIT - I'm using the Microsoft ILogger Abstraction for .LogDebug()

Solution

You can output the message-template (instead of the formatted message) using raw=true:

    <attribute name="message" layout="${message:raw=true}" />
